When it comes to ground beef, among the most versatile and beloved of ingredients, itâs not all about meatballs and burgers and chili. Psh, who are we kidding, yes it is! Few things excite us more than a couple of pounds of fresh 80/20 chuck, straight from the butcherâs loving meat-grinder, ready for our bidding.
When oceanic and oceanic plates diverge it creates mid ocean ridges!
Subduction boundaries occur where oceanic lithosphere is pushed beneath continental or oceanic lithospheres. Where two plates converge at an oceanic trench a subduction boundary is formed as cold oceanic lithospheres are pushed back down into the mantle. This happens because the oceanic plate is denser than the continental plate so, as they move together, the oceanic plate is forced underneath the continental plate. In this case, one plate overrides, or subducts the other, pushing it slowly downward into the mantle where it melts to form magma.
